  • 12dB/octave Butterworth crossover
  • High level inputs
  • Ultra compact chassis
  • Variable 4-6 volt hi level DC offset voltage input turn-on control
  • 1 Year Standard Warranty

Class-BR

U.S. Patent 8,212,620 B2

Stores energy and dynamically boosts rail voltage to create power on demand.

To achieve higher efficiency with lower distortion, Rockford Fosgate’s BR topology combines, cycle-by-cycle, an indirectly coupled high/low voltage rail linear topology.

This combination yields an unsurpassed power density (watts per cubic inch).

 

CEA-2006 Compliant

Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier’s output power ratings are REAL POWER numbers, not inflated marketing ratings.

Read CEA-2006 Amplifier Power Standards under Answer ID #199 in our Knowledge Base.

MEHSA3

MEHSA3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.

MEHSA3 (Maximum Efficiency Heat Sink Application – gen. 3) is a proprietary process that yields up to five times better heat transfer than traditional FET mounting techniques, using the exact same components.

A multi-layer insulated metal substrate operating with minimal thermal resistance spreads heat both downward & outward to quickly dissipate heat from each device across the heatsink.

This process combined with our optimized heatsink designs, DSM (Discrete Surface Mount) technology and MOSFET devices, allows Rockford Fosgate to squeeze more watts per cubic inch from every output device as well as provide consistent thermal stability.

The 3rd generation creates a dielectric layer between the ceramic topside and the aluminum base that retains all of the electrical isolation and capacitive coupling of the original MEHSA material increasing it’s thermal conductivity.

The higher power handling results in a 20% reduction in thermal impedance.

DSM

DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.

DSM – An industry-leading manufacturing process, DSM utilizes high-speed robotics, high-quality 1% tight-tolerance parts and large board traces.

The discrete components are laser etched to meet a particular value and a very low tolerance.

This lower tolerance improves the efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.

These superior components are used by aerospace, automotive, and cellular manufacturers.
